I think it would help greatly to (eventually😉) have access to:
Disable status of stuff for the Bubble enemies:
bool Link->SwordDisabled
bool Link->ItemDisabled
Or however ZC keeps track of the whole temporary/permanent thing.
In order to toggle between passive and active subscreen. Would return false if the subscreen is already moving, so it can't be set.
bool Game->SetSubscreenState(bool active)
Returns true if subscreen is active.
bool Game->GetSubscreenState()
The currently selected inventory item in the subscreen.
int Game->SubscreenSelected
So you can change which subscreen is displayed on the fly. (or at least read)
int Game->ActiveSubscreen
int Game->PassiveSubscreen
